SOP 3IX 0-0-53 Crystalline Potassium Sulfate — 1 lb
SOP 3IX is a high-purity crystalline sulfate of potash produced via ion exchange, delivering 53% soluble potash (K₂O) and 18% sulfate sulfur in an ultra-fine, rapidly dissolving form. With the lowest chloride content of any commercially available SOP and a very low salt index, 3IX is the preferred potassium sulfate for high-value crop production, sensitive hydroponic systems, and precision liquid blend formulation.
Key Features
- 53% soluble potash (K₂O) — highest K₂O content of any SOP formulation
- 18% sulfate sulfur — immediately plant-available sulfur co-delivered with potassium
- Ion exchange production — ultra-low chloride; lowest salt index of any SOP
- Crystalline form — very low SGN for rapid, complete dissolution in water
- Chloride-sensitive crop safe — ideal for berries, cannabis, tobacco, potatoes, and vegetables
- Liquid blend compatible — dissolves cleanly with no residue in fertigation and hydroponic systems
Applications
- Hydroponic and soilless nutrient programs
- Fertigation and drip irrigation systems
- High-value chloride-sensitive crop production
- Precision liquid fertilizer blend formulation
- Cannabis production — bloom and finishing stages
